Mark Haverkamp 43f2f3d343 [PATCH] aacraid: Fix for controller load based timeouts 
Martin Drab found that he could get aacraid timeouts with high load on his
controller / disk drive combinations.  After some experimentation Mark
Salyzyn has come up with a patch to reduce the default max_sectors to
something that will keep the controller from being overloaded and will
eliminate the timeout issues.
